Whether you are downsizing or simply want a more accessible shower setup, this guide walks you through the full picture — from how the process works to what qualifies someone an ideal candidate. Read on to see whether a tub to shower conversion is the right move for your home.
What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and hardware — is removed and replaced with a purpose-built shower unit. The complexity of the project is shaped by your existing bathroom plumbing configuration, your style choices, and whether you plan to expand the shower's usable area beyond the original tub's space.
On a mechanical level, the process involves rerouting the existing tub drain and supply lines, lifting the tub unit and any surrounding wall material that was tied to it, then building out the new shower base with a correct slope toward the shower drain. New waterproofing membrane is applied before any tile, stone, or prefab panel goes up. Plumbing is rerouted to accommodate the new showerhead height and any additional fixtures you choose.
The result is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done right is not just a visual change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.

- Stronger Home Appraisals — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion signals modern, move-in-ready conditions to future owners.
- Easier Cleaning — Shower surrounds and bases are typically faster to scrub and wipe down than a full-length bathtub with a surrounding tile enclosure.
- Custom Design Options — From subway tile surrounds to semi-frameless enclosures, a tub to shower conversion opens up many more design options than a standard tub surround.

- Long-Term Durability — When our team completes a tub to shower conversion, the structural components are constructed to hold up through years of daily use.
The Tub to Shower Conversion Project Step by Step
- In-Home Evaluation and Scope Review — A member of our team visits your home to assess your existing tub, plumbing, and bathroom layout. We discuss your wishlist and timeline so the proposal reflects exactly what you need.

New cement board or tile backer is screwed to the structural framing, and a full waterproofing membrane is applied across all wet surfaces. The drain area is graded toward the drain to ensure drainage.
- Installing New Shower Plumbing — Our plumbing team set the new rough-in plumbing according to your fixture selections. Whether you chose a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this stage.
- Applying Your Chosen Finish Materials — Our finish crew apply your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every tile edge is sealed and inspected before glass or curtain hardware is installed.
- Hanging Doors, Glass, or Hardware — Depending on your selected style, we hang your chosen enclosure system. Each component is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Quality Check and Project Sign-Off — Once everything is finished and installed, we perform a careful walk-through. All caulk joints at the base and wall corners are caulked with professional-grade caulk. We walk you through the finished shower and make sure everything looks and functions as planned.
